Now, 4D technology has been used to create a soft robot capable of analyzing the soil. Drawing inspiration from the seed structure of the South African geranium (Pelargonium appendiculatum), which ...

Using a new technique known as 4D printing, researchers can print out dynamic 3D structures capable of changing their shapes over time. Such 4D-printed items could one day be used in everything from ...

During the early stages of life, organs do not just appear in their final form. They take shape through a process of controlled bending, twisting, and folding. These changes help cells organize into ...

Combining materials with different swelling ratios creates structures that transform into tubes when exposed to water. (Courtesy: Yu Bin Lee) Materials that controllably change shape over time – often ...

Nowadays, 3D printing allows items to be created from a wide variety of materials — plastic, ceramic, glass, metal and even stranger ingredients such as chocolate and living cells. The machines work ...

Though the practice of 3D printing is still firmly entrenched in its journey from fledgling idea to emerging technology, news out of Harvard’s Wyss Institute this week proves innovation waits for no ...

Enter 4D materials, which are like 3D materials, but they change shape when they are exposed to specific environmental cues, such as light or water. These materials have been eyed by biomedical ...

New Rochelle, NY, November 2, 2017--A new study describes 3D printing of Shape Memory Polymers to produce active meta-materials that can be programmed to form versatile shapes and are then able to ...

New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a ...
